SASH-OPERATING DEVICE.

Specification of Letters Patent.

Patented Feb. 16, 1909.

Application filed March 19, 1908. Serial No. 422,108.

To all whom it may concern:

Be it known that I, LOUIS BARBIERI, a citizen of the United States,residing at New York, in the county of New York and State of NewYork,'have invented certain new and useful Improvements inSash-Operating Devices; and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to sash manipulating devices, "and particularly tothat type of device which the sashes are raised and lowered withoutengaging them with the hands.

The object of the invention is to provide a device of this characterwhich will be cheap to manufacture, which will be simple and efficient oeration, and which may be pro erly'reguated to determine the height of tesash and the frame. 7

Afurtherobject of the invention is the provision of means which willenable me to accomplish the above functions in such a niannerthat theparts will be easily and readily accessible for the purpose of repairingand re lacement of worn parts, thus obviating t e necessity of employinga skilled workman to re air any slight defect in the mechanism, suc as abroken cord or the like.

With these and other objects in view, the invention consists of certainnovel features of construction, combination and arrangement of parts, aswill be more fully described and particularly pointed out in theappended claims.

In the accompanying drawings, Figure 1 is a front elevation with partsbroken away, Fig. 2 is a vertical sectional view taken on the line 22 ofFig. 1, Fig. 3 is a horizontal sectional view taken on the line 33 ofFig. 1, Fig. 4 is asimilar view taken on the line 4-4 of Fig. 1, Fig. 5is a horizontal sectional view showing the arrangement of the upper pairof guide rollers, Fig. 6 is a horizontal section on an enlarged scalethrough the lower part of the window frame, the filling plate and silldrum being removed, Fig. 7 is a similar view with the sill plateremoved, Fig. Sis a similar view with the idle drum removed and parts insection, Fi 9 is a front elevation of the lower part of the frame, thefront plate being removed, Fig. 10 is a vertical sectional view taken onthe line 10-10 of Fig." 9,-Fig. 11 is a bottomplan view of the idle drumpartly in section, Fig. 12 is a sectional view taken on the line 12-12of Fig. 11 and looking in the direction of the arrow, Fig. 13 is avertical section taken on the line 1313 of Fig. 9 disclosing the pivotalmounting of the tripping device, Fig. 14 is a perspective view of one ofthe removable upper ends of the beads.

Referring more especially to the drawings,

1 represents an ordinary window frame hav-' ing its sides provided withlongitudinal grooves 2, which are covered with sash plates 3, havingguiding beads 4 upon which the sashes are adapted to run. These guidingbeads are provided at their ends with removable strips 5, each having attheir lower ends a tapered lug 6 to engage notches in the sash plates,and at their upper ends are lugs 7 adapted to engage a similar notch andto be engaged by a clamping screw. The auxiliary ends of the sash beadsare removable for the purpose of taking the sashes out of the frame whenit is found necessary for any purpose whatever, the guard rail 8 beingcut away, as shown for this purpose. At the top of the grooves 2 Iprovide a, double pair of rollers 9 and 10, two on each side of theframe for the reception of the elevating cords 11 and 12, which will behereinafter described.

The elevating cords 11 and 12 pass from their connection with the sashesover the pulleys down through the grooves 2 to a double pair of pulleys13 and 14, secured in the sill boxing 15, between vertical webs 16, andfrom thence to the winding drums 17 and 18, which are journaled upon thestub shafts 19 and 20, projecting from the bottom of the boxing 15, andbeing engaged with the apertures 20 in the sill plate 21, which overliesthe boxing and is secured thereto in any suit able manner. Both of thesedrums are similar, in that they each comprise a pair of plates joinedtogether by a peripheral web, around which the cords are adapted toswing, a series of teeth formed in the periphery of the upper plate anda spring held between the plates and keyed to the web at one end and atits other end to the stub shafts. These stub shafts are held stationarywith respect to the boxing so that the drums revolve around them as thesashes are lowered to wind up the springs to hold them under tension.

A tripping arm 22 is carried adjacent the winding drum 17, and has uponits inner end a gravity-pawl 23, which normally engages the teeth ofthis drum and rides idle there over when the sash is being lowered, thecords playing out of the drum at the time, and the spring being woundupto elevate the sides when the drum is released. opposite end of thistripping arm has engaging it a leaf spring 25, which forces the innerpawl end normallyinto engagement with the top of the drum so thatthepawl will properly engage the teeth at all times. The outer end ofthe lever beyond its spring engagement is provided with an upstandinglug screw threaded to receive the thumb piece 26, which passes throughthe front plate 27, to be in position for manual engagement.

Mounted upon the top of the drum 18 in slidable engagement with thestubshaft is a centrally squared arbor of an idle drum 28, which hasattached to it a spiral spring 29, which controls the idle drum 30. Thebottom plate of this drum. has projecting;

through its. lower face a series of spring pressed pawls 31, whichengage .thenotches 32, formed upon the upper face plateof the drum 18.These notches have a squared Wall at one end, and a beveling wall at theother end which permits the pawls 31 to ride freely out of the notch inone operation and to, engage the squared wall and rotate the drum18, Asuitable operating .cord 32*, is passed around the drum and around aguiding pulley 33, mounted upon a vertical stub shaft 34, projectingupwardly from the bottom' of the boxing between the two pulleys. Thiscordpasses around the pulley 33 over a pulley 35 carried by the frontplate and through the front plate where it is secured to an operatingring in this instance held in the mouth of a lions head carried upon thefront plate. This idle drum is held in engagement with the drum 18 byleaf springs 36, which are secured to the top face of the sill plate 21and passed through the apertures 36 therein.

A pair of lugs 37 and .38, the latter being removable, depend from thelower face of the plate 21, and are apertured to receive the pivotpintles 39, of a tripping device 40. This tripping device has its innerend spring pressed up into engagement with the sill plate 21 by a leafspring 41, and its outer end formed inthe shape of a semi-circle tosurround the idle drum 28 and to provide arms 42 and 43, which engagethe upper and larger disk of the drum, so as to raise it from itsengagement with the winding drum 18. A suitable gravity pawl 44 iscarried in the arm 43, so as to slip up and down in a bearing 45, formedat the end thereof, whereby it may engage the peripheral teeth of thedrum 18 to hold it in its wound up position.

Suitablepulleys46 and 47 'receive the cords travelin from, the sash ldrums and guide them to the pulleys 13 and 14. A suit The able fillingplate 48 is secured upon the sill plate 21 in anysuitable manner, and asill drum4'9 is slid thereover and secured thereto.

In.op.eration the device acts as follows: When itis'desired to raise thelower sash it is only necessary to press the tripping arm 22 V whichraises the pawl 23 out of engagement withtheteeth of the drum 17,thereby releasing it and allowing the spring to wind up upon the cordsso as to raise the sash. The sash may be lowered by simply pressingdownwardly upon the meeting rail. The cord at this time unwinding fromthe drum and the pawl 23 riding idly over the teeth of the drum 17. Ifit is desired to lower the upper sash the operating cord 32 is pulledout so as to rotate the idle drum 28 to force the pawls 31 intoengagement with the notches 32 so as to rotate the drum 18 and unwindthe cords thereon and wind up the spring therein, This action allows theupper sash to. descend by gravity, the pawl 44 of the tripping lever 40engaging the teeth of the drum 18 and holding it in rotated osition withits spring under tension. W en the cord 32 isreleased the drum rotateson its arbor back to its normal position with they spring unwound, thepawls 31 riding idly out of the beveled ends of the notches 32. When itis desired to raise theupper sash to normal position the tripping lever40 is operated by depressing theouter end thereof in the same mannerasdescribed in connection with the tripping lever .22, "i. e., by engagingthe thumb piece 40, which projects through the front plate 27. Thisaction raises the front end of the tripping lever and with it the drum28, so as to free the pawls 31 from the drum. The same action alsodisengages the pawl 44 fromthe teeth of the drum 18 and allows. thespring therein to wind up the drum andraise the sash.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to. without departing from the principle orsacrificing any of the'advantages of this invention as defined in theappended claims. i

Having thus describedmy invention, what I claim and desire to securebyLetters Patent 1s:

1. In a device of the-class described, the combinationwitha frame, of asash freely slidable therein, a spring drum, connection between the drumand the sash which normally holds the sash in raised position, means towind up the drum and simultaneously to free said connection to allow thesash to drop by gravity, means to hold said drum inwound up position,and means to release the drum ,and to render said operating meansinoperative.

2. lnfla device of the class describedthe combinationlwitha frame, of asash freely necting the spring drum of the sash and normally tending tohold the sash in raised position, a second spring drum having a paw andratchet connection with the first, means to rotate the second springdrum and thereby wind up the first spring drum and simultaneouslyrelease the cord to allow the sash to drop by gravity, means to hold thefirst sprmg drum in Wound up position, and means to simultaneouslyrelease said drum and render inoperative the ratchet connection of thesecond.

3. In a device of the class described, the combination with a frame, ofa sash freely slidable therein, a spring drum journaled below the sillof said frame, a cord connection between said drum and the sash, asecond drum mounted upon the top of the first and having a awl andratchet connection therewith whic allows the free rotation of the seconddrum with respect to the first in one direction and when rotated rotatesthe second drum in the opposite direction, means for operating thesecond drum to control the first whereby the sash may be lowered bygravity, a pawl to hold the first drum in operated position, a trippinglever carrying t e pawl and adapted to raise the pawl out of engagementwith the first drum and simultaneously to disconnect the ratchetconnection of the second drum therewith, and a thumb piece removablyconnected with said lever for operating the same.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
